I'm using Xcode 13.4.1 and targeting iOS 15.0. I have aSwiftUI app that crashes as soon as you click a button that changes a variable from true to false: Button("Close Side by Side Mode") { mainScreenRecs.isViewingSideBySide = false } This is the only place where the variable is changed; everything else is just SwiftUI reading the variable to determine whether to show views or not, like this: var body: some View {         VStack(spacing: 0) {                 HStack {                     if mainScreenRecs.isViewingSideBySide {                         Text(catalogModel.title)                     } When I look at the debug stack, I can see that the previous modification says LayoutComputer.EngineDelegate.childGeometries(at:origin:), which makes me wonder if it's related to SwiftUI: I see this in the debug output, which has the additional note about AttributeGraph: cycle detected through attribute, another possible SwiftUI problem: I tried wrapping this code in DispatchQuery.main.async, like this: Button("Close Side by Side Mode") { DispatchQueue.main.async { mainScreenRecs.isViewingSideBySide = false } } but it didn't help. Is it possible this is a SwiftUI bug? I hate to think that because it leaves me stuck without a solution, but I can't figure out what else I could check or try.

We are connecting to a web service that requires a certificate from a *.pfx. It works fine when the *.pfx is included in the app bundle and extracted from there, as mentioned in this discussion in thread #77694. The problem is, each device will have a unique certificate that will be pushed to it from an MDM; we don't have a single generic certificate that we can include in the bundle for all devices to use. For testing, we dragged the *.pfx certificate onto Settings, and it appears under "Configuration Profile", as shown in the attached picture. Questions: Is "Configuration Profile" the iOS equivalent of the Mac Keychain? When an MDM pushes a *.pfx certificate onto an iOS device, will it appear under "Configuration Profile"? Or somewhere else? The MDM isn't functional yet so we haven't seen how it works. If the answer to #2 is yes, is it possible to access the "Configuration Profile" certificates from within the app? Some articles I've read said this isn't possible due to security--you can only access your app's certificates. If this is true, how will the MDM make the certificates available to our app specifically and not just the device? Thanks so much for any help, James T

We have some PDFs that were created with JPEG2000 images in them (*.jp2 files). Using PDFKit, and also WebKit, the images in these PDFs in some cases don't display at all, and in others cases appear badly warped. You can view the PDF using either Adobe Reader, or the Chrome app, and the images appear fine, so it's clearly not an issue of a corrupt PDF. Also, 3rd-party commercial iOS controls like PSPDF and FoxIt display the images fine, so it's clearly an issue with PDFKit and WebKit. Any known workarounds?
